= This'invention relates to an automatic mule t1 ple punching -mach-1ne wh ch 1s automatic in its character by reasonofits simultaneous action in moving-the dies in and outof operative position in timed relation with each 7 other vhere'by it is possible tosimultaneous- 1O 7 bossing, the flange of an automobile lamp ly punch a plurality of'holes and emboss the metal about the flange of an article, such as a lamp body or the like. 1

Heretofore,.-in punching'holes in, or. em-

' body. or r'i-m' or-of an article of similar form,

of such an object or, embossing theumetal reit has been customary to manually position? the same over the die block for positioning and supporting while the punch is rammed home, whereupon the operator would manually move the work to a new position for punching holes or forming the m'etal'in another place. Thusythe operationot punch:

ing a plurality of holes around the periphery quired manual manipulation and several op.-

erations.

. It is the obj ect of this invention toprovide,

an automaticpunching machine which will receive such an article havlng an annular flange, positionfand securesthe .same move I f the die blocksbehind the flange=and thereafter ram the embossing or punching dies home. 'vUpon the diesbeing'jwithdrawn, the dieblocks are moved out of engagement so] as to'release the work and permit itsready' removal. This enables theentire process {to be, completed -m a sin greater accuracy.

Other features of the. invention reside more particularly in the construction and more fully set forth-and described.

I o

The jig is mounted upon aibolster block. 7 lt and is operatedin the" usual manner through theslide 15 mounted upon" the usualpress whichQis connected with the device throughthe connecting and operating link 16. Rotatably mounted upon thefront face =01 the ig and supported bythe shaft 17 to which it is keyed, there" is'an actuating-disk- ]18- provided with ajpluralit-y of cam slots 19 f so -formed that a portion thereof extendscon- I befhe'reinafter'more fully set forth.

'centrically with the direction of rotation while another portion extends inwardly at an {angle thereto,- for a purpose: which'will 1 The bodyiof the is'providedwith four I which there areslidably' mount'ed the punch lzeyways 20, as shown in Figs. 1 and 2,111, o

ly'ln andout with respect to the center of rotation of the disk'18 Each of said blocks 21-carries" a 911122 which extends through f its respect1v 'e' camj slot 19 and is surrounded by a roller 23. Mounted intermediate the 1 diskY18 "and each of the-blocks 21 there is a portion ofthe cam s1ots19 toward the pa.

ripherylof the dislnath'usinovingith blocks- I 21 and the die blocks 2% carried thereon radially outward along their respective key die block24 through which the pin 2 2 extends 1 so as to be carried thereby in' itsamove'mentl conforming to the action of the diskJand' -QQ in 2 and 4. Thus, the die block is moved into position behind the flange 13 of the work to be punched. Thereupon the continued rotation of the disk will cause the pins 22 to follow the concentric portion of the cam slots 19 so that this position is maintained during the punching operation. 7

The block 21 is provided with abushing 25through which the punch 26jextends and is reciprocably mounted Inasmuch as the die block 24 and the block 21 are connected together by the pin 22 their relative positions 7 are constantly maintained, and the die block is provided with an opening 27 to receive the punching end of the punch 26. As shown herein, the upper and lower punches are shaped to" punch rectangular holes in the work, whereas the side or lateral punches are designed to punch round holes. The punch 26 is caused to slide in the bushing 25 through the forward and rearward sliding movement of the block 28- which is prov'idedwith a T- slot 29 to receive the head 30 of the punch 26. This permits ofthe movement of the punch with respect to itsoperating block 28 and-in conjunction with the block 21 and die block 2%. The punch is moved in and out of opera tive position by the sliding movement ofthe block 28 which is actuated by the lnternal drum 81 whichis provided with cam-like-recesses 32. about its-periphery.

'saidcam-Ilike recesses extend about the pe; "riphery ofthe-drum in a plane parallel tothe face of the die, while another portion and con-j tinuation thereofextends forwardly at, an

. angle thereto, asishown by dotted lines .in Figs. 3 and t. Mounted in the slidingv block 28 there is a pin 38 which is locked in position by the lock not 3a which extends into the cam slot132 surrounded therein by the roller.

35. Thug-upon rotation of thedrum 31 in a counterclockwise direction, the first part of its. movement will have no eifect'upon the block 28 and punch by reason of the cam slot I extending in the parallelplane abovereferred to. However,

upon the continuation of the rotary movement the angular direction of the slotwill cause the pin and die forwardly intopunching position.

Elie drum 31 is keyed to the shaft 17 which is supported at its rear end upon the bracket 36in spaced relat1on to the rear face of the i 87 ,to whichthe Rigidly secured to the -shaft 17 intermediate the jig andbracket 36 there is an arm ly thearmB'T is causedto move from the position-shown indotted s'hownin dotted lines in Fig. 2, thus rotating the shaft .to that extent. ;Theshaft in turn likewise rotates to the sa-me eitent thefldrum 31 and disk 18' for actuating the die blocks and punches, as above described lines in Fig. 1 to that a H lt is important to notethat by reason of the ar n m t o the se t er @6 32; h

' Upon the return or upward'movement of the press the. reverse action is obtained so that the punch 26- is 'first pulled ,rearwardl y.

to force theblock 28 y 7 link 16 is pivotally connected. I Thus, upon the link being forced downward punches are maintained against theirpuncl ing movement while the die blocks are moved radially with the punches into inoperative position, as shown in Fig. l. Upon the continued movement of the shaft the die blocks willbeheld against further movementin their operative position while the punches are moved forwardly to punch the work, 7 operation, the work is placed between the blocks 11 when the operative parts of the punch are inthe positions shown in Figs. 1

and 3. Upon the downward movement of the press the disk 18 is rotated counterclocl-rwise causing the pins 22 tobe moved outwardly by the cam slots 19,.thus carrying the four die positions by reason of thepins 22 idling in the concentric portions of the cam during the first step or part of the movement tie pins 33 will ldle 1n the aligned portions of the slots 32 in the drum 31. Now, the pins the blocks 28am moved forwardly to force the punches 26 through the flange13 of the work 7 and into the "openings 27 of the the head .so that the punching operation is completedas.

toits normal position and thereafter the die blocks 24am moved inwardly to normalpo; V sltion so that thework 12 maybereadily removed.

. From the foregoing it willbe'observed that by one operation of'the press a series ofjholes are simultaneously punched in-the inwardly turned flange of the work. This not only obtains greater speed than heretofore,but more. accuracy in the spacing thereof- Wh le, as

hereinjshown, there are four punches, it wlll slots 19.1 Also r 33 proceed in the inclined cam slots32 so that V beapparent that anyaiuinber of punches may be employedas well ,as-anynumber. of die blocks. This may be obtained together with operationsrupon varyin'g sizes and shapes or work by altering or changing the'position of the supportingblocks 11'fas wellas the cam disk 18 and its associated parts.
